Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, pressure regulator test board pneumatic means, comprises air inlet cylinder clamp 1, cylinder clamp 2 of giving vent to anger, suspended body flowmeter 3, pressure regulator valve 4, T-valve 5, two-conductor line precision pressure sensor 6, datalogger 7, some ball valves, some exhaust boxs, some rectifiers; The one termination source of the gas of ball valve A8, the other end is divided into three tunnels, the first via is connected with air inlet cylinder clamp by ball valve B9, and the second tunnel is successively by being connected with air inlet cylinder clamp after pressure regulator valve, rectifier A10, T-valve, and the 3rd tunnel is connected with cylinder clamp of giving vent to anger by ball valve E11; The outlet of cylinder clamp of giving vent to anger is divided into three tunnels, and the first via connects two-conductor line precision pressure sensor, datalogger successively, and the second tunnel connects ball valve C12, suspended body flowmeter, ball valve D13 successively, and the 3rd tunnel connects ball valve F14, exhaust box C15 successively; Described T-valve is also connected with one end of rectifier B16, and the other end of rectifier B is connected with exhaust box B17, and one end that described ball valve B is connected with air inlet cylinder clamp is also connected with one end of ball valve G18, and the other end of ball valve G is connected with exhaust box A19; Described air inlet cylinder clamp is oppositely arranged with cylinder clamp of giving vent to anger.Connected by flexible pipe 20 between each connected parts.
Described air inlet cylinder clamp and cylinder clamp of giving vent to anger all are arranged on the operational platform, on air inlet cylinder clamp slip setting operation platform.Described air inlet cylinder clamp and cylinder clamp of giving vent to anger have included chuck, and chuck is provided with seal flange.
During use, first by all valve closings, and pressure regulator be placed on air inlet cylinder clamp and give vent to anger between cylinder clamp, the entrance of pressure regulator is just to the seal flange of air inlet cylinder clamp, and the outlet of pressure regulator is just to the seal flange of cylinder clamp of giving vent to anger.Then open ball valve A, T-valve is switched to cylinder side, by upstream inlet, air inlet cylinder clamp is moved, thus make pressure regulator be grasped tightly air inlet cylinder clamp and give vent to anger between cylinder clamp.
The stop valve of Non-follow control pressure regulator makes the valve port of pressure regulator cut out, then ball valve B is opened, if the inside of pressure regulator has the valve port of seepage or stop valve to be not closed completely, then gas will flow out from the outlet of pressure regulator, enter into pressure regulator downstream pipe, the reading of pressure transducer rises gradually by from original " 0 " value.If pressure sensor readings remains " 0 ", then can think that pressure regulator does not exist internal leak, stop valve sealing is qualified.
Open the stop valve of pressure regulator, open ball valve E, pressure regulator downstream pressure is made to be elevated to the operating pressure of default pressure regulator stop valve, then the cut-out spring of stop valve is regulated, until stop valve can cut off automatically, close ball valve E, open ball valve F by emptying for pressure regulator downstream pressure rear closedown ball valve F.Again open ball valve E, after making pressure regulator, pressure is raised to stop valve intensity pressure, sees whether stop valve can cut off.If stop valve can cut off automatically, then illustrate that stop valve is normal, if can not cut off, then carries out maintenance and inspection to the stop valve of pressure regulator.Repeat several times, until qualified.
Close ball valve E, ball valve F, open ball valve C, the top hole pressure after pressure regulator is adjusted to default pressure, read the flow reading of suspended body flowmeter, see whether within the scope of the effective discharge of design, if abnormal, then inspection and maintenance is carried out to pressure regulator.Repeat several times, until qualified.
Slowly close ball valve C, check the reading of pressure transducer, when reading no longer changes, see reading whether within the scope of the closing presure of the pressure regulator of design, if abnormal, then inspection and maintenance is carried out to pressure regulator.Repeat several times, until qualified.
Ball valve A slightly can reduce pressure to source of the gas, and pressure regulator valve is for regulating flow by the gas of ball valve A and pressure, and rectifier is for eliminating the flow state of unstable gas, and exhaust box is for weakening the dynamic property noise of gas.Described T-valve is also connected with one end of rectifier B, and the other end of rectifier B is connected with exhaust box B, the flow state arranging the instability can eliminating the gas flowing to T-valve of rectifier B and exhaust box B, meanwhile, weakens the dynamic property noise of gas; One end that described ball valve B is connected with air inlet cylinder clamp is also connected with one end of ball valve G, the other end of ball valve G is connected with exhaust box A, and the dynamic property noise that the flowing arranging flow instabilities state and the gas that can make gas flow before entering pressure regulator of ball valve G and exhaust box A produces is alleviated or eliminates.
Then, repeatedly finely tune pressure regulator valve top hole pressure, when finely tuning, the gas flow flowing to pressure regulator is different at every turn, and the lifting position of the float in suspended body flowmeter also can be different, and the rate of discharge of the pressure regulator recorded by datalogger and top hole pressure are also different.A period of time is kept during each fine setting, observe the lifting position of float in suspended body flowmeter, whether the rate of discharge of pressure regulator that datalogger is recorded and top hole pressure stablize, whether rate of discharge and top hole pressure in order to judge pressure regulator are stablized, if basicly stable, then can think that pressure regulator is qualified.Repeatedly finely tune, debug out the maximum exit pressure levels of pressure regulator.
The object arranging two-conductor line precision pressure sensor in the utility model is to revise rate of discharge and top hole pressure, the revised top hole pressure of datalogger record and rate of discharge.
After detection terminates, first close all valves, then open ball valve G, ball valve F, the test gas in emptying pipe, then switches to rectifier B by T-valve, and the gas in emptying air inlet cylinder clamp, makes cylinder bounce back, take off pressure regulator, complete detection.
The utility model structure is simple, simple to operation, can detect the stability etc. of the closedown performance of the pressure setting of the sealing of pressure regulator and stop valve, pressure regulator and stop valve, pressure regulator, the discharge characteristic of pressure regulator, the top hole pressure of pressure regulator, measuring accuracy is high, thus ensures the quality of pressure regulator.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
